1'0 all-l wlmm it may concern.-

Be it known that I, BUDD J. Jonas, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illin'ois, have inver ted a new and useful Improvement in Line Structures i or Electrical Distribution, of which the following is a specification.

This invention relates to line structures for electrical distribution, and particularly to structures that are utilized for railway service.

The object,of the invention is to provide desirable supporting devices forconductors of high voltage electrical energy which shall embody effective insulating means.

A further object of the invention is to provide apparatus of the character specified in which the insulators are so located as to be free from danger of injury throughthe action construction, combination, location and ar-' .rangement of parts, all as Wlll be more fully hereinafter set forth, as shown in the accompanying drawing and finally pointed out in the appended claims.

1 Referring to the accompanying drawing and to the various views and reference signs appearing thereon-Figure 1 is 'a view, in s1 e elevation, of a supporting pole, showing the application thereto of a conductor-supporting device embodying theprinciples of Fig. 2 is a top plan view of the same. Fig. 3 is a broken, detail, sectional view showing the means for securing the in- Fig. 4-1s sulator to the supporting bracket. a detail view in section through the insulator, Fig. 5 is a perspective-and partially diagrammatic view of a portion of a line structure that embodies the principles of my invention.

The same part is desi'gnatedby the same reference sign Wherever it occurs throughout the severalviews.

Infthe distribution of high tension energy for operating electric cars, or'for other-purposes, porcelain or glassinsulators are generally utilizedgto efliciently insulate the line conductors; Inthe operation ofrailways which em loyftrolle s for 'makingcontact with over ead con uctors, the insulators that are usually employed are exposed tothe' pounding action of the trolley and also to the danger of being struck by it in caseit becomes detached from the conductor. Glass or porcelain insulators, as generally used, often fail to successfully withstand the strains caused by thepounding action of a trolley when operating at high speeds along the conductor supported by such insulators. When the insulators arebroken, the operation of the line is interrupted, and if the conductor falls to the ground, as it is likely to do, it be-- comes a source of danger to pedestrians and others using the streets which are occupied bythe hue structure. This is especially true where a high-tension conductor is suspended from supporting brackets, in accordance with the practice heretofore generally employed.

It is among the special purposes of my present inventionto provide supporting apparatus for conductors carrying high-tension currents, in which glass or porcelain insulators may be utilized without danger of be ing struck by a trolley in, case it jumps from the trolley wire or conductor, and in which the arrangement is such that the insulators are relieved from the strains which are caused by the pounding of the trolley as it passes along the conductor. These objects may be accomplished by means of many specifically difi'erentconstructions and arrangements, and, consequently, while I have shown and will now describe one construction and arrangement for accomplishing the desired objects, I desire it to be distinctly understood that my invention is not to be limited or restricted to the exact details of: construction and arrangement disclosed.

Referring to the accmnpauying drawing, A designates a glass or, porcelain insulator, which may be of any suitablciorir.

B designates a supporting plate having a seat, formed by an oilset flange C (see Fig. 4:) in which the insulator is located and in which it is secured by suitable means, such, for example, .as a layer of cement I). The supportin plate B is provided with a lateral fiange E to afi'prd means for supporting the same u on a suitable bracket or other device, wIierebyI the insulator may be supported in convenient relation with respect, tor instance, to a railway track.

In the form shown,

to which I do not desire 'to be limited or restricted, F designates a supporting pole, to which is suitably secu'red an arm or bracket Gr, upon the outer or free end of which theinsulator is mounted.

the insulator laterally so that it may be set in any desirable position with reference to the track, I'mount it upon the supporting arm or bracket G for movement laterally with respect to the conductor orsupporting wire. lateral movement may-be accomplished in many specifically different ways. In the particular form shown, to

which, however, I do not desire to be limited or restricted, 1 provide the bracket or arm G with an elongated opening H, upon theup-f per surface of the bounding edges of which rest the lateral flanges E of plate B. I have shown the supporting arm or bracket G in the form of an angle-bar, the outer end of which is bent or doubled upon itself to form an elongated opening H, as clearly seen in n Fig. 2, t is horizontal flange of theangle-bar forming a supporting surface upon which the 2 5 lateral flanges E of plate B rest. In order. to secure the plate B to the supporting arm or bracket G while permittin adjustment laterally along opening H, bo ts J may be employed, which project through holes in the flanges E and have hooked ends which engage the edge of the vertical portion or flange of the angle-bar G '(see Fig. 3). this construction, the insulator supporting plateB and the insulator are supported upon 3 5 the upper surface of the supporting arm-or bracket and arei'herefore out of danger of being struck by the trolley in case it becomes 'disengaged'from the conductor. It will also be seen that provision is made for lateral adjustment of i-he insulator and its support along the supportingarm or bracket G, while at the same time the insulator'is held-or clamped in adjusted position upon the supporting arm or bracketG. The insulator A is provided with suitable means to receive a wire K, such, for instance, as a seat L in its top. In. practice, however, wireK is not utilized as a conductor, but serves as a mes-I senger or supporting wire for a conductor M, along which the trolley operates, theconductor M carrying. the high-tension current and being supported by or suspended; from the.

messenger or supporting wire K in any suitable or convenient manner.

; 5 in order to avoid rigidity as between the conductor M and its supporting or messenger 'wire K, the suspending connections N by which the conductor M is. supported are flexible, thoughl do not desire to have my inven- 9 tion limited or restricted in this'respect. By

making such suspending connections flexible,.

relative movement between the. conductor M and messenger or supporting wire K is poss-ible, whereby the ounding action of the troli5 ley. upon the con uctor M isnot transmitted in order to provide means for adjustmentoff -of my invention.

By means of desire to secure by Letters Patent, is:

Preferably, and

. said messenger wire.

.wires, an arm, a messenger wire supported to the supporting or messenger wire 'K and, consequently, breakage of the insu-lators by such action is avoided. 'In practice, I pro pose to employ a. plurality of the suspending connections N between adjacent insulators A, so that if the conductor is broken at any; point, or a suspending connection N becomes detached'or is broken, the conductor M .Will still be maintained out of danger'of accidental contact with pedestrians or others who 7 5 may be beneath it.

It is obvious, that the suspending connecti ons N may be applied in any suitable or con venient manner as suspending supportsdor: the iconductor M. The brackets or arms G may be secured and braced tothe poleor other support F inanyconv'enient manner: I have shown a brace-rod P-extending downwardly and outwardly from the pole or support F to the :bracket or arm G to serve as an 8 5 auxiliary supporting means. i

While I have described a specific means for mounting the insulators, it is obvious that many variations and changes in the details of construction and arrangement may readily o s'tjggest themselves to-persons skilled in the art which will fall within the spirit and scope I do not desire, therefore, to be limited or restricted totheexact details shown and described. But 5 Havir'ig now set forth the object and nature my invention, and a construction. embody ingthe principles thereof, what I claim as senger wire supported by said'insulator, a

trolley wire, and means for suspending said trolley wire from said messenger. w1re.- I
